Process the drained tofu in a food processor until creamy. Add the flour, yeast, ketchup, parsley, sesame seeds, taco seasoning, cayenne, salt and pepper; process until smooth. Add the vegetables and process until the vegetables are finely chopped and incorporated.

Form the mixture into 4 patties and dredge in wheat germ. Heat a teaspoon of oil in a large nonstick skillet over medium heat. Add the burgers and cook for 5 minutes. Turn and add another teaspoon oil; continue cooking 4 minutes, or until heated through. (Serve on toasted buns with condiments.)
